<p>The apparatus comprises a buffer hopper (12), the entrance of which communicates with the exit (10) of a dedusting device (1). The buffer hopper (12) is supported by at least one weighing means (13, 14). The buffer hopper (12) possesses at its exit end a discharge means (15), the flow of which is controlled by a variable-speed motor (18). A regulating module (20) makes it possible to compare a signal representing the mass of the buffer hopper (12) with a predetermined fixed value and to prepare a control signal for the motor (18), so as to keep the quantity of powdery material contained in the buffer hopper (12) constant. <IMAGE></p> |
